The insert carries a dual-layer TiAlN and AlCr2O3 coating applied via PVD process, which supports thermal stability and wear resistance at elevated cutting speeds. It features a 35-degree diamond (V) shape with a neutral hand orientation, a 1\/64-inch corner radius (0.0156 inches), and an inscribed circle of 3\/8 inches (0.3750 inches). The UM chip breaker geometry is optimized for stainless steel, with secondary suitability for superalloys and titanium. Screw-on insert holding keeps the insert indexed and secure during aggressive passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is specified for turning stainless steel as its primary workpiece material, with superalloys and titanium as secondary materials. That combination of substrates makes it well-suited for aerospace, medical device, and process-industry component machining where tight tolerances and difficult materials are standard. The CoroTurn 107 series is commonly used in positive-rake toolholders for light-to-medium cutting depths. The UM chip breaker geometry controls chip formation in gummy, work-hardening materials where chip management is critical to surface finish and tool life.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDual-layer TiAlN and AlCr2O3 PVD coating for heat and wear resistance in hard-to-machine alloys\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond (V) insert shape provides a low cutting force profile and access in tight clearance zones\u003c\/li\u003e\n  \u003cli\u003eUM chip breaker geometry engineered for stainless steel and superalloy chip control\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method (clearance code B, tolerance code M) for repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert; neutral hand for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eISO designation VBMT 16 04 04-UM 1115 for cross-reference to equivalent holders and inserts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CoroTurn 107 series positive-rake screw-on toolholders that accept VBMT-style inserts.

Use the manufacturer-specified torx or hex key to torque the clamping screw — avoid over-tightening, which can crack carbide inserts. Inspect the pocket seat and screw threads for chips or damage before seating a new insert. After indexing, confirm runout and offset values at the CNC control before resuming cutting.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: VBMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: VBMT 16 04 04-UM 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 1115\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (V), 35-degree included angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN and AlCr2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.638 inches (16.21 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches, 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Superalloy and Titanium (S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.24 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5755680\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51751398900018,"sku":"5755680","price":426.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13cda698584605ece421afa8ce4e8c0f_19702b2e-f179-4b57-8240-b36beca74cf6.jpg?v=1788923226","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5755680-turning-insert-vbmt331-um-1115","provider":"Voomi Supply","version":"1.0","type":"link"}
